Abstract (sommario):
A number of studies have been published in the last few decades on Pleistocene palaeo-temperature reconstruction based on isotopic studies on deep sea cores and ice core records from Greenland. Such temporal high-resolution data represents northern hemispheric circulations and has to be reconfirmed through the study of terrestrial archives in order to recognise the character of such fluctuations in different regions. Loess-palaeosol sequences (LPSs) are suitable to interpret them as palaeoenvironmental archives, because loess is a widely distributed terrestrial deposit and is datable using lum

Abstract (sommario):
Soil collapse is amongst one of the most significant ground related hazards. A collapsible soil, in particular loess, typically has an open-structure and collapse occurs when as a consequence of the addition of water and/or load the particles rearrange to form a more dense fabric. Collapse leads to a suite of problems for buildings and infrastructures built on or in collapsing soil. Treatment to mitigate collapse often involves in densification. However, such approaches have been reported not always effective enough to combat the problem. This stems from a lack of understanding of soils’ geoch

Loess has a metastable structure and undergoes structural hydrocollapse when loaded and wetted, leading to subsidence and damage of overlying structures, which presents enormous engineering problems in many countries in the world.

The dispersive and erodible nature of some loess soils on the Port Hills results in a variety of mass movement, surface and sub-surface erosion features.

Abstract (sommario):
The loess deposits of the Port Hills, Canterbury, are subject to erosion by natural processes. Urban development of the Port Hills has encountered difficulties due to loess erosion, and in some instances, contributed to erosion. Lime stabilisation is one remedial method that can be used to reduce erosion problems. This necessitates investigation of the changes to soil properties and strength gains that occur to the loess with the addition of lime. An erodible loess colluvium, from a subdivision with a history of erosion problems, was stabilised with 1%, 2.5%, 5%, 7.5%, and 10% hydrated lime,

This thesis project has examined the moisture dependency of shear strength in the loess soils of Banks Peninsula. These dominant silt materials are generally regarded as having an angle of internal friction between 25 and 30°, and cohesion of zero, when the soil is saturated. However, soil behaviour in terms of slope stability would appear to support a cohesion value higher than zero as vertical cliffs of loess can be seen to stand indefinitely. It is agreed that loess soils upon saturation do show very low shear strengths, but these soils rarely become saturated due to their low permeability

Loess is a well sorted, fine grained, windblown (aeolian) sediment and deposits as a blanket over large areas, reaching from a few centimetres to several hundreds of meters in height and can drape large landscapes in form of mountains. During a more humid and warmer climate, redox conditions are changed in the loess deposits, with greater seasonal moisture creating greater soil formation (pedogenesis), i.e. palaeosol.  The Chinese Loess Plateau is dominated by the East Asian monsoon climate, and consists of an alternating Loess-palaeosol Formation, spanning back to at least the whole Quaternar
